Carbide Thread Milling Cutters

Dormer's range of versatile thread milling cutters support the production of high quality internal threads in most materials.

Thread Milling is a method of producing a thread with a milling operation via a CNC machine capable of making circular paths (spiral interpolation). Numerous benefits compared to conventional threading include:

•          Same tool can be used to produce numerous thread diameters (as long as the pitch is the same)

•          Same tool can be used for both left and right hand thread production and G(BSP) can be used to create both internal and external threads

•          Smaller chips, promoting problem free threading and reduced down-time

•          Tolerance adjustments can be made using exact calculations

•          Full thread to the bottom of the hole

•          Very secure method of creating threads in difficult to machine materials

Dormer's thread milling range is identified by the following product code:

•  J2** (Thread Milling Cutters)
